As with the video, you can use audio filters via -af but it is not necessary. You may also want to use -channels 6 to exact all the channels of a 5.1 DVD or changing the bit rate. You should repeat the command for every audio track you want, so we will have. oac lavc -lavcopts acodec=vorbis:abitrate=224 -channels 2 -srate 48000 -o "$AUDIOLANG".avi Mencoder -dvd-device "$ISO" dvd://"$TITLE" -alang "$AUDIOLANG" -chapter "$CHAPTER" -ovc frameno \ The command follows (replace the variables with desired values):

Here we compress with the Vorbis algorithm, but you may want to check the MEncoder manual Also, it is necessary to use scale=$WIDTH,-10 with $WIDTH as -1 to keep the original width or a new, usually smaller, width: it is necessary since the H.264 codec uses square pixels and DVDs instead use rectangular pixels. It is important that you use harddup as the last filter: it will force MEncoder to write every frame (even duplicate ones) in the output. (If you do so, remember to use the same frame rate everywhere including in the commands to rip audio.) You can also use any other of the filters MEncoder has to offer, like pullup,softskip or you can change the frame rate using -ofps.

You may want to scale down the movie with -vf scale=$WIDTH:-10,harddup the width of the movie will become $WIDTH (keep $WIDTH a multiple of 16: 640, 480, or 320 are usually fine), the height will be correctly calculated in order to keep the aspect ratio. For example, a movie with a black border should be cropped with -vf crop=$X:$Y,scale=-1:-10,harddup with the proper values instead of $X and $Y (see cropdetect in the MEncoder manual). You can play with the -x264encopts options and the -vf filters to improve the quality or reduce the file size. This will create a video.avi file containing the video. Mencoder -dvd-device "$ISO" dvd://"$TITLE" -chapter "$CHAPTER" -nosound -ovc x264 \ # Second pass: here we compress the video track using the information from the first step.

We will not extract any audio for now.Ĭommands follow remember to replace the variables with the proper values: The H.264 encoder is usually used in two passes: the first reads information about the movie, the second uses that information to encode. We will use mencoder (part of mplayer package) for ripping and encoding and mkvmerge (part of mkvtoolnix package) for making the. mkv file with an H.264-encoded video and any number of Vorbis-encoded audio tracks. This information can also be found here where it better explained, although non-specific. Similarly, to list output audio codecs, run However, there are MANY more options available.įor input formats, MEncoder can use any format that MPlayer can play, so to verify whether it will work with your video, just try playing it in MPlayer. This is basically how one converts a video. The default output formats without any options are MPEG-4 for video and MP2 for audio. Mencoder movie.mpg -o movie.avi -ovc lavc -oac lavc So to convert movie.mpg to movie.avi with MPEG-4 Part 2 video and MP2 audio, the command is Mencoder original_video.mpg -o new_video.avi -ovc output_video_codec -oac output_audio_codec
